Build a Faraday Motor with Your Students!
Posted on January 11, 2012 by Dr. Joel Bryan
In 1820, Danish physicist/chemist Hans Christian Ørsted noticed that when current from his Voltaic pile was switched on and off, a compass needle placed near the wire deflected from true magnetic north. Within a few months of careful study, he deduced that a magnetic field circles a current-bearing wire.
